TLDR
In this paper, the authors considered a Brownian particle in a periodic potential under heavy damping and showed that if the particle is subject to an external force having time correlations, detailed balance is lost and the particle can exhibit a nonzero net drift speed.Abstract:
We consider a Brownian particle in a periodic potential under heavy damping. The second law forbids it from displaying any net drift speed, even if the symmetry of the potential is broken. But if the particle is subject to an external force having time correlations, detailed balance is lost and the particle can exhibit a nonzero net drift speed. Thus, broken symmetry and time correlations are sufficient ingredients for transport.read more

Stokes efficiency of temporally rocked ratchets
TL;DR: In this paper, the generalized efficiency of an adiabatically rocked ratchet with both spatial and temporal asymmetry was studied and an analytical expression for generalized efficiency in the deterministic case was obtained.

StructureMan: A Structure Manipulation Tool to Study Large Scale Biomolecular Interactions.
TL;DR: In this article, a Structure Manipulation (StructureMan) program is introduced to operate the structures when studying the large-scale biomolecular interactions. But, due to their large scales, many biomolescular interactions are difficult to be simulated via all atom models.

Ratcheting fluid with geometric anisotropy
TL;DR: In this article, two asymmetric, sawtooth-like structures are placed facing each other and form a corrugated fluid channel, which is then forced to open and close periodically.

Converting external potential fluctuations into nonzero time-average electric currents using a single nanopore
Vicente Gomez,Patricio Ramirez,Javier Cervera,Saima Nasir,Mubarak Ali,Wolfgang Ensinger,Salvador Mafe +6 more
TL;DR: In this article, the authors demonstrate directional electrical transduction from fluctuating external signals using a single nanopore of conical shape immersed in an ionic aqueous solution, and characterize experimentally the average output currents obtained by the electrical rectification of zero time-average input potentials.

Realistic Models of Biological Motion
Imre Derényi,Tamás Vicsek +1 more
TL;DR: In this paper, a statistical physical description for the description of motion of molecular motor proteins has been developed, which is referred to as ''thermal ratchets'' and can be used for the modeling of biological motion.

The Fokker-Planck Equation: Methods of Solution and Applications
TL;DR: In this paper, the Fokker-Planck Equation for N Variables (FPE) was extended to N = 1 variable and N = 2 variables, where N is the number of variables in the system.
